Anti-reflective film

An anti-reflective film including:

• a hard coating layer and a low-refractive layer,
• wherein the low-refractive layer contains hollow organic nanoparticles and solid inorganic nanoparticles that are dispersed in a binder resin, wherein the hollow inorganic particles are in a higher amount by weight than the solid inorganic particles
• wherein the low-refractive layer includes a first layer containing at least 70 vol % of the total volume of solid inorganic nanoparticles dispersed in the binder resin and a second layer containing at least 70 vol % of the total volume of hollow inorganic nanoparticles dispersed in the binder resin, and
• wherein the first layer has polarization ellipticity measured by ellipsometry using a Cauchy model represented by the following General Equation 1, in which A is 1.0 to 1.65:
